Method and system for supporting multiple display devices

摘要

A method and a system for supporting multiple display adapters in the WDDM architecture are provided. A driver wrapper serves as the interface between the OS and the display drivers. The driver wrapper hides the display drivers from the knowledge of the OS and provides the standard display driver interface (DDI) to the OS. In the view of the OS, the driver wrapper is the single common driver which receives requests from the OS. The driver wrapper dispatches the requests from the OS to the display drivers and relays responses from the display drivers to the OS. The driver wrapper of the present invention is compatible with multiple distinct display drivers.
